	abstract = {A conformal array antenna has been designed in the waveguide technology in order to obtain an omnidirectional radiation pattern in the azimuth plane at the Ku-band. The antenna shape is a regular prism, where the single radiating elements, which consist of a rectangular waveguide ended on a cavity{\textendash}slot, are placed on the planar faces of the prism. The physical dimensions as well as the number of faces of the regular prism have been optimized following the conformal array formulation in order to achieve a minimum ripple omnidirectional pattern. An eight-faced regular prism with an apothem of 20.6 mm has been selected as the radiating structure. The single elements are fed by an eightway radial waveguide power divider symmetrically excited by a 50-Ω SMA input port. The use of waveguide technology to design the single elements and the feeding network makes the conformal array suitable for low losses and high-power applications. Several prototypes have been manufactured in order to experimentally validate the antenna performance. An omnidirectional pattern with a maximum ripple of 1.6 dB in the azimuth plane, 95.3\% efficiency, and 11.7\% input matching bandwidth has been measured..},

	abstract = {A conformal array antenna fed by a radial waveguide divider has been designed in order to obtain an omnidirectional performance at Ku band. The single radiating elements consist on a waveguide ended on a cavity-slot and they have been placed on the regular prism faces conforming the final antenna shape. The array dimensions as well as the number of faces have been optimized to generate a maximum ripple in the omnidirectional pattern, obtaining an eight-faced regular prism antenna with an apothem of 20.6 mm. The single radiating elements are fed by an equal power eight-way radial waveguide divider. The use of waveguide technology makes the structure suitable for high power applications.

An omnidirectional pattern with a maximum ripple of 1.6 dB in the azimuth plane, a total efficiency of 98.8\% and an input matching bandwidth of 11.7\% has been measured.},

	abstract = {A conformal array antenna for omnidirectional coverage in the azimuth plane at Ku band is presented. An eightfaced prism structure has been used to obtain the omnidirectional radiation pattern following a maximum theoretical ripple criterion. The radiating element consists of a rectangular waveguide ended on a cavity-slot. An equal power eight-way radial-waveguide divider has been designed to feed each radiating element. The use of waveguide technology minimizes the propagation losses and makes the structure suitable for high power applications with omnidirectional coverage requirements. The achieved simulation results show a maximum realized gain of 2.4 dB, a maximum ripple of 1.5 dB for the omnidirectional pattern and a matching bandwidth of 16.2\% around 17 GHz.},

	abstract = {Power division/combination is a very important function for achieving high-performance power amplification in microwave and millimeter-wave systems. This function allows the use of simpler individual amplifiers to provide microwave/millimeter wave high power signals. In this paper we address the development of divider/combiners in waveguide technology for large number of ports. Radial waveguide dividers will be studied, starting from the S-parameters representing the N-port waveguide junction, and ending with the full-wave simulations. Two different designs in this technology are studied, radial divider and conical radial divider. The experimental evaluation will come from a prototype at Ku-band, fabricated and tested in order to validate the design.},
